No. Or rather, you *could*, but you'd have to make a special NSCell that loaded the xib file, added all the views as subviews of the table view (in appropriate places) and conspired somehow to manage the set of views so that you didn't just end up adding/creating more and more views as the user scrolls around. The root of the problem is that NSCell is not a view, and moreover the table view may use the same cell over and over when drawing its rows. > Now what implications will this have if I using core data?, I will have an > NSArryaController as the dataSource for the table view, so my guess is that > when returning the cell instance, I must get the object from the > arrangedObject array of the NSArryaController at the given row. > > am I right, wrong? what else am I missing? Wrong. NSCell is not a view. There is not one NSCell per table "cell"; generally speaking, NSCells are re-used, and so the data is set before drawing using -setObjectValue: or similar. If you do need views in a table view (e.g. because you want a progress indicator, or you want to do mouse tracking or something), there are plenty of examples: <http://www.google.co.uk/search?hl=en&source=hp&q=nsview+in+nstableview> For many applications, though, this is unnecessary and you should just use appropriate NSCell instances; if the provided NSCells and NSFormatters aren't sufficient for you, it's usually possible to write a custom NSCell that draws whatever it is you need.
